Configuring the Daikin ENVi Thermostat ‐ Preferences

The first step after installing the Daikin ENVi thermostat is to configure the thermostat settings for the Indoor Unit.

Intelligent Eye: Menu > Settings > Preferences > Intelligent Eye > Yes/No

Some models of the Indoor Unit include an intelligent eye, an infrared sensor that detects room occupancy. It adjust the set point by 3.6°F (2°C) if no movement is detected in order to save energy (+3.6°F/+2°C if cooling,-3.6°F/-2°C if heating).

To use intelligent eye, you must enable this option in the Daikin ENVi thermostat and then enable it with the Daikin wireless remote controller. If enabled, the thermostat’s Smart Recovery and Temp Alert functions are not available.

By default, intelligent eye is disabled on the thermostat.

Do NOT enable the intelligent eye with the Daikin wireless remote controller when it is disabled on the thermostat as this may cause suboptimal operation and result in invalid recovery and alert messages. Also, if an auxiliary heater is configured, enabling intelligent eye may energize the auxiliary heater more often than would normally be required.

Configuring the Daikin ENVi Thermostat – System Settings

System Settings: Menu > Settings > Installation Settings > System Settings

Min Cycle Off Time Sets the minimum equipment off time between cool cycles: 240 to 900 seconds (default is 240 seconds).

Min Cycle On Time Sets the minimum equipment run time in cool mode: 1 to 20 min (default is 3 min).

Min Outdoor Temp Disables the compressor when the outside air temperature reaches the configured minimum setting. This performs two functions. It prevents the compressor from running when the outdoor temperature is too low, thus resulting in damage to the compressor. You can also set this value to determine when you want the auxiliary heat (if installed) to engage to help meet the set temperature. The temperature range is adjustable from -10 to 65 °F (–23.3 to 18.3 °C) or disabled by default.

This feature uses the Internet to obtain the current outdoor temperature. If no Internet is available, the Outdoor Unit’s temperature sensor is used instead.

Cool Differential Temp The minimum difference between the current temperature and set temperature before the system calls for cool. A smaller difference means shorter cycle times, whereas a larger difference results in longer cycle times. The temperature range is adjustable from 0.5 to 3 °F (0.3 to 1.7 °C) in 0.5°F (0.3°C) increments.

Cool Dissipation Time The amount of time the fan will run after the cool has been turned off. Running the fan for a period of time allows for any cooled air left in the ducts to circulate throughout the home. The time is adjustable from 0 to 900 seconds (default is 0 seconds).

AC Overcool Max When using the AC to dehumidify, the setting configures how many degrees below the current set point the thermostat will run in order to reach the dehumidify set point. Options are Disabled (default) and 0.5 to 3 °F (0.3 to 1.8°C) in 0.5 F (0.3°C) increments.

Heat Differential Temp The minimum difference between the current temperature and set temperature before the system calls for heat. A smaller difference means shorter cycle times, whereas a larger difference results in longer cycle times. The temperature range is adjustable form 0.5 to 3 °F (0.3 to 1.7 °C) in 0.5°F (0.3°C) increments. The default offset is 0.5°F (0.3°C).

If the Indoor Unit is AC only and an auxiliary heater is configured, this option appears under the Aux Heat Settings menu.

Heat Dissipation Time The amount of time the fan will run after the heat set point has been reached and the call for heat has been turned off. Running the fan for a period of time allows for heated air to circulate throughout the home. The time is adjustable from 0 to 900 seconds (default is 0 seconds).

If the Indoor Unit is AC only and an auxiliary heater is configured, this option appears under the Aux Heat Settings menu.

Configuring the Daikin ENVi Thermostat – System Settings (continued)

Indoor Unit Temp Offset Depending on its type, the Indoor Unit uses a temperature offset for the heating set point, taking into consideration the higher sensing temperature. The Daikin ENVi thermostat applies the offset to the set point which is sent to the Indoor Unit. The offset should be 3.5°F (2.0°C) for wall-mounted and ducted indoor units, and 0°F (0°C) for floor-standing indoor units (available in the future). The offset range is adjustable from 0°F (0°C) to 5.5 °F (3.0°C) in 0.5°F (0.3°C) increments to allow for future indoor unit expansions. The default offset is 3.5°F (2.0°C).

Heat Pump to Aux Temp Delta The minimum difference between the current temperature and the set temperature that will activate Aux Heat (regardless if the maximum run time of the heat pump was reached). Options are Auto (default) and 1 to 10 °F (0.6 to 5.6 °C).

Only visible if Indoor Unit supports heat and an auxiliary heat source is also configured.

Heat Pump to Aux Runtime The maximum amount of time the heat pump will run before engaging Aux Heat. Options are Auto (default), Disabled, and 10 to 180 minutes.

Only visible if Indoor Unit supports heat and an auxiliary heat source is also configured.
